Common Note on Printed Wiring Boards:
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
a
: Through hole.
•
f
: internal component.
•
: Pattern from the side which enables seeing.
Common Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in
Ω
and
1
/
4
W or less unless otherwise
specified.
•
%
: indicates tolerance.
•
f
: internal component.
•
C
: panel designation.
•
A
: B+ Line.
• Total current is measured with CD installed.
• Power voltage is dc 4.5 V and fed with regulated dc power
supply from external power voltage jack.
• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : CD PLAY
∗
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.

: CD
Caution:
Pattern face side: Parts on the pattern face side seen from the
(Side B)
pattern face are indicated.
Parts face side:
Parts on the parts face side seen from the
(Side A)
parts face are indicated.
Note:
The components identi-
fied by mark
0
or dotted
line with mark
0
are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque
0
sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.
